Summer is over. I'm curious to hear any impressions of the r5 cam. I thought but now people would have been sharing their results. If anyone replies please include brief description of engine build. Another question,,,, what cam are the general fastest cars using? I know the f4 is a great cam. Im trying to decide on a cam for a built 2.5 in a sc. Menegon 287 big valve head, 3076r, bmf, tu header, 5 speed, ect. Thanks in advance.
